Well, Drupal 8 is right around the corner. There's a lot of effort to get a beta release out, there are trainings being developed and books being written. But when I thought about the best way to teach myself about Drupal 8, the obvious choice was to install it and play around, investigate the issue queues, try to help in Sprints, and pick a small site to just bite the bullet and convert.
So since I only maintain one site, I guess this will have to do.
I am going to blog a bit about how I'm going about converting the site.
